For example, in the program-defined function redefinition example, the my-unless macro can reside in its own package, where user-defined-operator is a private symbol in that package. The symbol user-defined-operator occurring in the user code will then be a different symbol, unrelated to the one used in the definition of the my-unless macro.
The rsx! macro in the Dioxus front-end framework is an example of a function-like macro. [129] [130] Theserde_derive macro [131] provides a commonly used library for generating code for reading and writing data in many formats, such as JSON. Attribute macros are commonly used for language bindings, such as the extendr library for Rust bindings ...
Tokio is a software library for the Rust programming language. It provides a runtime and functions that enable the use of asynchronous I/O, allowing for concurrency in regards to task completion. [2] [3] [4] Tokio was released in August 2016 for Rust, a general-purpose programming language.
A macro is a piece of code that executes at compile time and either performs textual manipulation of code to-be compiled (e.g. C++ macros) or manipulates the abstract syntax tree being produced by the compiler (e.g. Rust or Lisp macros). Textual macros are notably more independent of the syntax of the language being manipulated, as they merely ...
A parameterized macro is a macro that is able to insert given objects into its expansion. This gives the macro some of the power of a function. As a simple example, in the C programming language, this is a typical macro that is not a parameterized macro, i.e., a parameterless macro: #define PI 3.14159

Rust for Linux is an ongoing project started in 2020 to add Rust as a programming language that can be used within the Linux kernel software, which has been written using C and assembly only. This project aims to leverage Rust's memory safety to reduce bugs when writing kernel drivers . [ 1 ]
